    Windows: Build against SpiderMonkey 52
    
    This is done so that people can also test Windows builds for gjs that is
    based on SpiderMonkey 52.
    
    As the upstream libffi is not very well maintained for Windows/MSVC, we
    are also switching to use the Centricular fork for libffi[1], which will
    also be the case for the upcoming stable releases for GLib (i.e. GObject)
    and GObject-Introspection.
